IP SNMP credentials
NOTE
The Management application supports SNMPv1, SNMPv2c, and SNMPv3.
The Management application requires SNMP credentials to obtain information from devices and to
deploy configurations to devices. Because different devices may have different credentials,
discovery can store many sets of credentials to make sure that the correct credentials are available
when contacting a device.
Two types of credentials can be used for discovery: SNMPv1 and SNMPv2c read-write community
strings and SNMPv3 read-write credentials. If SNMPv1 or SNMPv2c is enabled on a device, use
read-write community strings. If SNMPv3 is enabled on a device, use SNMPv3 read-write
credentials.
When a device is contacted, discovery tries the credentials in the order that they are listed on the
SNMP tab on the Global Setting tab of the Discover Setup - IP dialog box until it finds one that
matches the credentials on the device. Discovery tries the SNMPv3 credentials first. If none of the
SNMPv3 credentials work, discovery tries the SNMPv1 and SNMPv2c credentials. Discovery must
detect the read only credentials to proceed to the read-write credentials. If discovery does not
detect any read-write credential, the device may still be discovered; however, all write operations
through SNMP (such as configure device) do not execute properly. When a match is found, the
device becomes discovered to the Management application, and its properties are saved in the
database so that it can be managed by the Management application.
Devices not discovered through profile-based discovery can be added individually. For more
information, refer to
“Adding an IP device to discovery” on page 121.
Adding SNMPv1 and SNMPv2c credentials
If SNMPv1 or SNMPv2c is enabled, or if you want to use community strings to gain access to the
device, define community strings.
To add a SNMPv1 or SNMPv2c read-write community string, complete the following steps.
1. Select Discover > IP Products.
The Discover Setup - IP dialog box displays.
2. Click the Global Settings tab.
3. Click the SNMP tab.
